TYPES OF GASKET MATERIAL

NON-METALLIC Non-metallic gaskets can be made from CNAF (Compressed non-asbestos fibre), PTFE, Rubber, Teflon or Graphite. These gaskets compress easily with low tension bolting. They’re generally used for low pressure applications and low temperatures. One exception is graphite gaskets, which can be used for temperatures as high as 460 degrees centigrade.

METALLIC Metal is used for ring type joints in high-pressure applications, such as oil and gas supply production. RTJs are also used on valves and pipework, assemblies in refineries and other process industries. They seal by an initial line contact or a wedging action as the compressive forces are applied. Metal ring type gaskets are available with oval and octagonal cross sections. Octagonal include the BX type designed to seal pressure up to 20,000 psi, in accordance with API 6A pressure ratings.

COMPOSITEComposite gaskets are a combination of metal and non-metal material based on service requirement. Spiral wound, Metal Jacketed, and Kamprofile gaskets are well known in the composite gasket category. They’re used in a wide range of pressure and temperature services.Composite gaskets are cost effective as compared to metal gaskets, but careful handling is required. Composite gaskets are used on raised face, male-female, and tongue-and-groove flanges.

A flange leak results in loss of product and energy, sometimes with disastrous consequences. No plant operator wants leaking of toxic or hazardous material that can harm humans or the environment. The right type of gasket helps to achieve a reliable seal to prevent leakage from the flange joints.

The Function of a Gasket is to create and maintain a static seal between two stationary, imperfectsurfaces of a mechanical system, designed to contain a wide variety of liquids or gases. The gasket must be able to maintain this seal under all the operating conditions of the system including extremes of temperature and pressure. The performance of the gasket is affected by a number of factors. All of these factors must be taken into consideration when selecting a gasket.


UIP has the technology to automate just about any shape required for your application. Non-metalic materials are available in widths up to 60 inches and sheet lengths of up to 50 feet depending on the product. For oversized gaskets, UIP has the capability of creating custom segmented gaskets for ease of handling and installation.

In order to ensure a successful seal many factors must be considered. The gasket material must be resilient and rugged enough to overcome any irregularities in the mating surfaces; resist extrusion and creep; and prevent blowouts under various operating conditions. Material thickness is also important when choosing a non-metallic gasket. The thinnest material that a flange application will allow should be considered however, the material should be thick enough to compensate for any surface irregularities or flange parallelism. Thinner gaskets can handle an increased level of bolt load and will reduce the amout of bolt stress that is lost due to relaxation. Additionally, thinner material reduces the gasket area which limits the amount exposed to attack from internal pressure and/or an aggressive application.

UIP suggests contacting one of our knowledgeable team members to select the correct material for your application. There are a number of gasketing materials available and new materials emerge often. Material specifications are also available in our literature and on our website to assist in proper material selection.

In addition to choosing the correct gasketing material, proper installation is crucial to ensure a leak free BFJA (Bolt Flange Joint Assembly). Most commonly, when there are leaks in a flange, it is assumed that it is due to a “gasket failure” however, that is rarely the case. The vast majority of the time, leakage occurs as a result of improper installation. Follow these basic guidelines when installing a gasket in a BFJA:

1) Properly inspect the gasket to ensure it is in good condition. The dimensions should be verified including the I.D., O.D., Bolt pattern (if applicable), and the thickness of the gasket. A visual inspection of the flange sealing surface should also be done to ensure it is free of any debris, lubricants and/or defects. All fasteners should meet the requirements including material, length, thread pitch and nut thickness. Lubricants should not be used to temporarily hold a gasket in place. 2) Align the gasket properly to be concentric with the flange ID and avoid protrusion into piping flow path, ensure gasket remains in proper place during assembly and that flanges are properly aligned and parallel to each other. 3) Bolts must be tightened in incremental steps to arrive at the target stress level using a properly calibrated load control device such as a torque wrench, or a stud tensioner. During the incremental torqueing steps, it is good practice to measure the flange gap at a minimum of four points at 90 degrees to each other around the flange OD at each step to assure even loading.Note: For soft gasket materials, one of the major factors is the creep relaxation of the gasket. Creep effects are accentuated at elevated temperatures, with the net result that the compressive load on the gasket is reduced, thus increasing the possibility of a leak. Consequently, UIP International, Inc recommends that fasteners should be re-torqued (to the recommended torque at ambient temperature before the process is energized) 24 hours after the initial assembly.**UIP strongly encourages the reader to reference FSA/ESA document (FSA0009) FSA/ESA Gasket Installation Procedures

Bolting should be of sufficient strength to achieve proper compression of the gasket, to not onlyseal the joint, but to maintain the seal without exceeding the yield strength of the bolts beingused. Torque values are based on using ASTM A193 Grade B7 studs and 2H heavy hex nuts lubricated with never seize. Since sheet gasket materials have micropores, they must be sufficiently compressed to reduce porosity. Without adequate compression the system pressure can force the contained fluid into the gasket and degrade it. Therefore, when installing the gasket it is important that good technique be followed including cleaning the flanges, inspecting the flange face and the bolts and bringing the flanges together parallel and in stages. Many field problems arise from improperly installed gaskets. According to the Fluid Sealing Association (FSA,) incorrect tightness is the leading reason gasketed joints fail. This can be prevented by following good bolting practice.

TORQUEAfter installing a new gasket or seal it’s essential to tighten the fasteners with a torque wrench that’s been recently calibrated. Without this, it is impossible to know if the joint has been tightened to the required level.Friction between the nut, washers, flange faces and thread increases the torque measured at the wrench, possibly resulting in insufficient clamping force being applied to the gasket. Avoid this by applying a thin, uniform coating of high quality lubricant to the underside of bolt heads, nuts and washers and the thread itself.

Take care to keep it off the gasket.

TIGHTENING SEQUECEThe gasket must be compressed uniformly to avoid material displacement. It’s also important to avoid

deforming the flange faces. There are two aspects to consider: the bolt pattern and the tightening sequence.

BOLT PATTERNTo bring the joint together, fasteners should be tightened in opposite pairs. Start at 12 o’clock and then move to 6 o’clock. Then halve the angle between them, moving to the 3 and 9 o’clock pair. Halve the angle again, going to the pair closest to 1:30 and 7:30. Keep repeating until every bolt has been tightened.

TIGHTENING SEQUENCEFollowing the pattern described above, insert the bolts and run up the nuts by hand.Set the torque wrench to 30% of full torque and, using the pattern, tighten each fastener.Repeat with the torque wrench at 60%.Repeat again with the torque wrench at 100%.

Make a final pass, this time in a circumferential direction, ensuring each fastener is at the required torque.

DO THE JOB ONCEReplacing gaskets and seals can be expensive, so whenever joints are made in pipes and ducting it’s important to ensure they don’t leak. One factor in achieving a good joint is to follow good bolting practice. Control the torque applied, the bolting pattern and the tightening sequence to avoid leaks.

General: These Conditions of Sale (“Conditions”) apply to the sale of goods by UIP International, Inc. (“Seller”). The Seller will not be bound by any other agreements, contract, modification or waiver of these Conditions unless expressly approved in writing by an authorized employee or agent of Seller.

Delivery: Unless otherwise agreed in writing, delivery is F.O.B. Seller’s warehouse for sales from Seller’s stock, and delivery is F.O.B. Purchaser’s warehouse for direct container shipments. Regardless of whether delivery is F.O.B. Seller’s warehouse or Purchaser’s warehouse, the responsibility for payment of freight, insurance, duty and other costs shall be determined by the agreed terms of the particular sale. Seller has choice of routing and may deliver goods in more than one lot. Each lot shall be deemed a separate contract and paid for separately. Any delivery made within thirty (30) days of the agreed date shall constitute timely delivery and delivery of goods any time thereafter shall be timely delivered unless Seller receives written notice of cancellation by certified or registered mail five days prior to shipment. Seller shall be permitted quantity variations of ten percent (10%) more or less than specified, with the price being adjusted accordingly.
